Unless I missed it there is no power key on the keyboard delivered with my
2001 G4/466 (109 keys including volume/mute/media-eject, but nothing
looking like a power key.)

If somebocy is going to touch the input layer, I would like the raw
keyboard mode to stay raw. Right now in some configuration combinations
there is no difference between raw and medium-raw (used by X). They both
return medium-raw keycodes, I can't get to the scancodes.
